Synthesis of bio-templated clickable quantum dots and a dual-emitting organic/inorganic complex for ratiometric fluorescence visual assay of blood glucose

We report the fabrication of a dual-emitting organic/inorganic complex, which was constructed by DBCO/FAM-GOx and bio-templated N 3 –QDs. The DNA-bridging FAM@GOx–QDs complex could be applied for the differentiation of diabetic and healthy people by the naked eye.
